Abstract
A system for delivering radiation dose, includes a gantry to move about a target to be irradiated and a radiation source mounted to the gantry and directed inward toward the target, The system further includes a collimator mounted to the gantry and in front of the radiation source, the collimator to shape a radiation beam directed at the target, wherein the collimator is to modulate a sub-beam intensity of the radiation beam across a plurality of sub-beams that subdivide a fluence field into a two-dimensional (2D) grid, and wherein a plurality of independent two-dimensional (2D) sub-beam intensity patterns are delivered from a plurality of gantry angles while the gantry moves continuously.
